The paper deals with space vector pulse width modulation (SVPWM) technique for vector controlled of two-phase disk synchronous machine (TPDSM). It is supposed that machine is supplied by VSI three-leg inverter. A reference voltage vector located in the irregular hexagon is realized by adjusting six space vectors and two zero vectors. The switching sequence for the digital SVPWM technique and the scheme...
The paper deals with combined real-time model of PM synchronous motor for sensorless position control. Real-parametric-and real-time model could be ideal tools for both control and simulation of the PMSM position drive. Unfortunately that idealized model doesn't exist so far. Such a model has to face following serious problems: it must be excited and synchronized by real input including non-linearities...
This paper presents a complex solution for whole speed range sensorless control of interior permanent magnet synchronous motor (IPMSM) drives. To cover an entire speed range of IPMSM without position transducer, different sensorless techniques must be employed. Design and implementation of sensorless techniques for different operating speeds are described in this paper. Presented application has been...
The paper deals with real-time estimation of PMSM rotor position, which is based on the new, virtual HF injection signal method. The main idea of that is subtraction of virtual injection voltage from real stator voltage. This voltage is acting on PMSM model and causes a virtual current response. After subtraction of acting model current from measured real stator current we obtain the virtual HF injection...
